In general, I think this idea makes sense. House pipes are usually sold by established pipe shops, and they have an interest in finding good pipes as house pipes, especially to get new smokers into pipe smoking so the shops have repeat business from satisfied customers. They may not be loss leaders, but they are usually moderately priced and sourced from quality pipe makers.
My first pipe was a Tinder Box St. Ives, purchased about 1978 and still looking and smoking strong, sourced from a French maker, perhaps Chacom or Charatan. Iwan Ries had excellent house pipes sourced from Edwards under their Benton line, oil cured Algerian briar, and they too are still going strong and look great. Today the IR pipes are sourced from Genod, and they also look first rate.
A few house pipes come from unexpected sources, like those from Disney theme parks and L.L. Bean.
Like any estate pipes, some would be in better repair and better maintained than others. Since these are often bought by new pipe smokers, they may have suffered some neglect or abuse, like bad reaming or over buffing. But in general, I think this is a promising path to a good rotation of pipes.
